I think Tether is positioning for a monetary system that becomes more dollarized for transactions but less dependent on dollar assets as the ultimate store of value. USDT converts global demand for digital dollars into demand for short term T bills, supporting the Treasury front end and reinforcing dollar hegemony. But Tether then uses part of the yield from those dollar assets to accumulate physical gold, effectively hedging the long term fiscal, inflation and geopolitical risks of the system it profits from. The possibility they appear to be hedging is not the end of the dollar but fiscal dominance or financial repression where persistent deficits, structurally higher inflation and eventual Fed intervention erode the real value of sovereign claims. Stablecoins could become even more important for payments and collateral while investors increasingly prefer gold for long term savings and reserve protection. In that world Tether wants T bills for liquidity and redemption, but gold for protection against sovereign and monetary risk. The dollar could win the payment system while gold simultaneously wins a larger share of the savings system.
